Oscillators – TC-40.000MCE-T Application Field and Working Principle

Oscillators are electrical circuits that can generate a periodic voltage or current waveform of specific frequency and amplitude. There are many different types of oscillator, each with a different application field. One such type is the TC-40.000MCE-T oscillator, which is widely used in telecommunications, radio frequency (RF), and digital signal processing (DSP) applications.

The TC-40.000MCE-T oscillator is a voltage-controlled, surface-mount package oscillator (VCO) comprised of dielectric films and resistor elements. Its frequency bounds are 40.000 MHz to 40.999 MHz, but the frequency range and stability can be configured to achieve accuracy levels up to ±0.5ppm. This is done by replacing the resistor elements with temperature-stable surface-mountable parts.

The TC-40.000MCE-T oscillator can be used in a variety of applications, including digital systems synchronization, broadband signal distribution, frequency hopping and spread spectrum tuning, cellular networks, Wi-Fi, navigation and positioning, and chip-level and system-level self-testing. In telecommunications systems, it is also used to provide a timing reference for OFDM (Orthogonal Frequency Division Multiplexing) modems.

Working Principle

The working principle behind the TC-40.000MCE-T oscillator is based on the fact that the frequency of a VCO can be varied over a range of frequencies by changing the voltage applied to the chip. Specifically, the TC-40.000MCE-T oscillator uses a voltage-controlled resistor (VCR) circuit which alters the resonance frequency of the oscillator when a control voltage is applied. The oscillator also features a built-in phase detector which can provide an output signal indicating when the frequency of the oscillator is in sync with an external clock signal.

The TC-40.000MCE-T oscillator also incorporates a temperature compensation circuit. This ensures that the oscillator\'s output is stable across various temperature ranges and that the frequency will remain within the specified range of operation. This is done by monitoring the temperature of the oscillator and adjusting the VCR circuit accordingly.

The TC-40.000MCE-T oscillator is an ideal choice for applications that need precise frequency control, as it offers excellent accuracy, stable operation, and a wide operating temperature range. It is well suited for systems that require frequent tuning and re-tuning such as those used in a digital broadcast environment. In addition, it has a very small form factor and can be installed in cramped spaces with ease.
